Hi all, In case anyone noticed/was wondering why things were running a bit slowly through TCL last night, we were receiving somewhere >1Gbit of DoS traffic (mostly large TCP, random ports) across a couple of links which got a bit saturated. As soon as it was brought to the network team's attention, the target (a poor DSL customer, I don't think DSL supports 1Gbit yet!) was null routed. --David Robb

And it's back again, even bigger this time. Filters are in place, but if anyone notices things being a little slow, this is probably why. --David

Yeah, we've (FX Networks) been hit by a couple over the last few days. Tonights one was particularly bad. And I have heard of another couple of ISPs that have been targeted as well (well, customers thereof). Anyone else? Is this a bit of a trend starting?
